Here, we can make 2 points 30 feet below the surface of water 10 seconds after he entered the water  100 feet below the surface of water after 40 seconds So, we have (10,30) and (40,100) Slope = y2-y1 / x2-x1 So, lets substitute the values of the slope m = (100-30)/ (40-10)      = 70/30     = 7/3 m = 2 1/3  or  2.33
